The term telecommunications is derived from “tele”, meaning at a distance, and “communications”, meaning exchanging of information. The history of electronic communications has thus far been applied to the exchange of spoken, visual, and or textual information between pairs of people, pairs of machines, and people and machines. The role of telecommunications has been to provide a medium for the...

In this paper, we describe how satellite communications may contribute to disaster management. During emergency situations, satellite communications present many advantages in supporting or replacing a terrestrial infrastructure (if any) subject to destruction or saturation. However, devising the right deployment model deserves close scrutiny in order to fit the responders’ needs and sustain fi...

The lower power consumption and lower mass of high-bandwidth optical telecommunications relative to RF telecommunications make laser communication technology extremely attractive for returning data from future NASA/JPL deep-space probes. JPL is building a research and development optical communications telescope laboratory (OCTL) at its Table Mountain Facility in Southern California to evaluate...
